Today the Ninth Circuit denied rehearing en banc in an important immigration case. Mike Kagan and I had filed an amicus brief urging rehearing. The panel opinion had made a mess of Loper Bright.

We did get three judges dissenting, and Judge Bumatay kindly gives our brief a shoutout in his dissent:

New draft on @ssrn.bsky.social: Stare Decisis and the Missing Administrability Inquiry

By Professor @chrisjwalker.bsky.social and @andrewshammond.bsky.social (@iumaurerlaw.bsky.social)

@ssrn.bsky.social: papers.ssrn.com/sol3/papers....
Screenshot of the following text: Stare Decisis and the Missing Administrability Inquiry New York University Law Review (forthcoming 2025) U of Michigan Public Law Research Paper No. 25-004 40 Pages Posted: 7 Aug 2025 Last revised: 11 Aug 2025 Andrew Hammond Indiana University Maurer School of Law Christopher J. Walker University of Michigan Law School Date Written: August 06, 2025 Abstract Administrative law is undergoing a tremendous amount of change. Presidential administrations have abandoned long-held practices and embraced new strategies to make policy through adjudication and regulation. Meanwhile, the Supreme Court has reworked foundational principles of federal administrative law including agency independence, adjudication, and legal interpretation. What does the pace and degree of change in administrative law mean for the federal courts? We posit that some answers lie in the Supreme Court’s decision in Kisor v. Wilkie and its application in the lower courts over the last five years. In Kisor v. Wilkie, the Court was asked to reconsider its longstanding precedents concerning judicial deference to federal agencies’ interpretations of their own regulations. The result was a splintered decision that produced more questions than answers. Justice Kagan, writing for the plurality (and in parts, the Court), reaffirmed those precedents, including Auer and Seminole Rock, but also clarified and expanded the ways in which such deference should be constrained. Justice Gorsuch penned the principal opposing opinion, arguing that the Court should abandon Auer deference entirely. Chief Justice Roberts cast the deciding vote based on stare decisis, suggesting that “the
